Abstract

A pressure sensor for measuring a pressure of a fluid, the pressure sensor including: a sensor element for measuring the pressure of the fluid; a control and / or evaluation circuit for controlling and / or evaluating a measuring signal of the sensor element; a circuit carrier, the control and / or evaluation circuit being disposed on the circuit carrier; a carrier element, the circuit carrier being fastened on the carrier element; and a housing element, the carrier element together with the circuit carrier being fastened in the housing element in a form-locking and / or force-locking manner, wherein the carrier element is configured in one piece from an electrically non-conducting material.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a pressure sensor for measuring a pressure of a fluid and to a method for producing a pressure sensor for measuring a pressure of a fluid.BACKGROUND INFORMATION[0002]Various (high) pressure sensors are believed to be understood. Patent document DE 10 2015 226 115 A1 discusses a pressure sensor. The sensor comprises a control and / or evaluation circuit for controlling and / or evaluating a measuring signal of the sensor element. The control and or evaluation circuit is disposed on a circuit carrier, which in turn is fastened on a carrier element. The carrier element is configured in two parts, namely, an electrically conducting part and an electrically insulating part, the electrically conducting part being connected to ground.[0003]The disadvantage here is that the carrier element is technically elaborate and the production of the carrier element is elaborate in particular due to the two-part structure of the carrier element....
